The P or N after the name indicates DIP package

Where else to find chips

Hopefully we (and other nice people) will be able to keep the distributor links current. But if we cant you can always search at http://www.findchips.com or http://www.octopart.com for other distributors such as Arrow, Avnet, Future, Jameco, etc. If you have a non-US distributor you use please add the links below so people outside the US can buy from their local shops.

Motor control

Notes on using the SN754410 v L293D: Some people use the SN754410 motor driver chip because it is pin-compatible, has output diodes and can provide 1A per motor, 2A peak. After careful reading of the datasheet and discussion with TI tech support and power engineers it appears that the output diodes were designed for ESD protection only and that using them as kickback-protection is a hack and not guaranteed for performance. For that reason Adafruit kits do not come with the SN754410 and instead use the L293D with integrated kickback-protection diodes. If you're willing to risk it, and need the extra currrent, feel free to buy SN754410s and replace the provided chips!

Only the L293D(N), includes kickback diodes so you'll need 'em! You can use Schottky diodes such as 1N5818 (preferred) or 1N4001s

"The MAX038 is (was) a high-frequency, precision function generator producing accurate, high-frequency triangle, sawtooth, sine, square, and pulse waveforms with a minimum of external components. The output frequency can be controlled over a frequency range of 0.1Hz to 20MHz

"The SN76477 'complex sound generator' was a sound chip produced by Texas Instruments (TI). The chip came to market in 1978, and TI production of the part ceased some time ago. More recently, a 100% compatible version, identified as ICS76477, has been listed as 'in stock' by at least one US-based component stockist. The chip was typically used as a sound effects generator in arcade games & toys and for hobby projects."
